WRENCH.

Application filed August 16, 1923.

2' '0 all whom it may concern Be it known that I, BYRON R. ARMs'rRonc, a citizen of the United States, and a resident of Delphos, in the county of Allen and State of Ohio, have made an Invention Appertaining to a Wrench, which invention is fully set forth in the following specification.

My invention has for its object to provide an efficient wrench for disconnecting nuts and bolts, and particularly for unscrewing nuts from the bolts, and wherein a simple means is provided for removing the nut from the wrench. The invention is particularly of value when embodied in a brace wrench.

Wrenches containing my invention may partake of different forms, and to illustrate a practical application of the invention I have selected one of the wrenches as an example and shall describe it hereinafter. The wrench selected is illustrated in the accompanying drawings.

Figure 1 of the drawings is a side View and partly sectional view of the wrench. Fig. 2 is an edge view. Fig. 3 is a sectional view taken on the line 33 indicated in Fig. 1. Fig. 4 is a sectional View showing an extreme position of the nut ejecting means.

The brace 1 is formed preferably of a metal tube bent to conform to the usual shape in which braces are made. One end is provided with the usual rotatable knob 2 having an axis of rotation in line with the center of the nut or bolt that is to be unscrewed by the wrench. The other end of the brace is provided with the head 3 having a socket 4. The socket 4 is made to conform to the shape of the nuts and the shape of the heads of the bolts that the wrench is designed to operate upon, either to screw or unscrew. Thus the socket may be in the form of a hexagon or a square and of any desired size.

In the use of a wrench of this type it is very common that the nuts become wedged in the socket or by reason of dirt or foreign material the nuts stick in the socket, and in order to enable rapid and efficient use of the wrench in unscrewing a number of nuts in succession I have provided a means whereby the nut may be readily ejected from the wrench, the means being located in a position where it will not interfere with the operations of the brace wrench and yet Serial No. 657,667.

in a position where it may be easily manipulated in order to eject the nuts. A washer 5 is secured to the end of a rod 6 having a diameter substantially that of the bore of the tube from which the brace 1 is formed.

The washer 5 and the end of the rod 6 are held normally near the bottom of the socket 4 in order that the nut may be engaged by the wrench. When it is desired to eject the nut from the wrench after it has been unscrewed the rod 6 is pushed towards the open end of the socket. In order that the shank of the wrench, that is, the part between the crank and the head 3, may be free from any obstructions and in order that it may be grasped and freely rotated in one hand by the other in the manner well known in the art. The rod 6 is connected by a flexible steel wire 8 to a finger piece located on the side of the crank near to the head 8. This will position the means for operating the wire 8 and the rod 6 on the side of the crank away from the operator.

The wire 8 is located within the tubular bar from which the brace 1 is formed and extends around the curve or bend 9 of the brace. It is connected to a rod 10 which is located in an opening 11 formed at a slight angle to the portion of the tubular passageway within the brace 1, and so as to reduce the bend and change of direction caused by movement of the wire 8 when the washer 5 and the rod 6 are manipulated to eject the nuts. Furthermore, the position of the opening 11 also positions the rod 10 so that its projecting end will lie close to the side of the crank farthest from the operator when using the wrench. The rod 10 is provided with a finger piece 12 which is secured to the end of the rod. The finger piece 12 is somewhat saddle-shaped so that when it is pressed it will be turned by its movement over the bend 13 of the brace and thus prevent engagement of any part of the finger piece 12 with the brace, it being held substantially in a proper position by the wire 8 that is bent around the bend 9 and the shape of the disc 5 which is in the form of a square and substantially fits the socket 1. Thus turning of the rods 6 and 10 is prevented.

I claim:

In a wrench, a tubular brace, a head havg a ocket connected to the brace, a, d sc located normally at the closed end of the socket, a rod connected to the disc, a "wire extending alon the brace and following a curve of the crank of the brace and connected to the said rod, a second rod connected to the Wire and a finger piece located on the end of the last named rod, the side of the crank of the brace located nearest the head having an opening extend ing at a sllght angle to the tubular opening of the brace for receiving the last named rod.

In testimony whereof I have hereunto signed my name to this specification.

BYRON R. ARMSTRONG.
